From 0 to 100 is a systems problem

Happy New Year & Welcome back!

Before anything else, a bit of context. From 0 to 100 is where I think in public. It’s where I connect with people I admire, exchange ideas, and unpack what actually helps businesses move from where they are to where they want to be, especially when the path isn’t linear.

This year, that thinking takes a more concrete shape.

My goal is to publish at least two high-quality podcast conversations under the From 0 to 100 umbrella, long-form, thoughtful, and grounded in real experience. It’s a space for learning, but also a way for me to earn from and alongside people who genuinely inspire how I build.

Feel like listening to one of the episodes? Check these “From 0 to 100M” conversations with:

• Gabriela Constantinescu, Co-founder & CPO, Chambr

• Oana Jinga, Co-founder & Chief Commercial and Product Officer, Dexory

• Silvia Carasel, Project & Marketing Manager

• Andrea Piazza, Angel Investor, Consultant & Author

• Ravi Kumar Sapata, CEO and Founder of PropTech Buzz

• Charis Stengos, Field Sales Representative, Google

Now, zooming out.

January is when ambition gets loud.

In real estate, ambition usually looks like more projects, more markets, more volume.
In tech, it shows up as more features, more experiments, more velocity.

Last year taught me that neither works without intent.

We’re building a technology platform for real estate, and one thing became very clear: software doesn’t magically fix fragmented markets. If anything, it exposes inefficiencies faster. Shipping more code without clarity doesn’t create leverage, it creates complexity.

My biggest learning is this: getting from 0 to 100 isn’t a growth problem. It’s a systems problem.

What actually moved the needle was being intentional about the system underneath everything:

• whom it’s built for,

• which workflows truly matter,

• and which problems are structural versus cosmetic.

Once we started thinking in systems, not features, not deals, things simplified. The product got sharper. Adoption got clearer. Conversations shifted from “what else can this do?” to “this fits how we actually work.”

That’s when From 0 to 100 stopped being about speed and started being about sequencing.

In real estate, trust compounds slowly.
In software, leverage compounds fast.

The challenge and the opportunity is designing technology that respects both.

This year, I’m not optimizing for shipping more. I’m optimizing for building the right system, one that can carry real volume, real capital, and real people through it.

I don’t know exactly what 100 looks like yet. We did manage to power close to $606M of real estate transactions in 2025. Here’s to more.

I’m very clear on how we’re engineering our way there.

More soon,
Irina
